Strap for DS Action Diver

The lug width is 20mm. Measurement is taken internally, from one lug to the other, perpendicular to the case. This non-standard dimension requires bespoke straps specifically engineered to ensure correct insertion into the case lugs without forcing or excess play.

Selection depends on intended use: alligator or vegetable-tanned calf leather for formal elegance; olive green or grey NATO for military aesthetic; vulcanised rubber (FKM) for humid or aquatic environments. Choice must balance functional requirements with visual coherence against the brushed stainless steel case.

Use a spring bar tool (small lever instrument), inserting the tips into the lateral holes of the lugs and pressing gently downward to compress the internal spring. With the lug raised, remove the old strap and insert the new one, ensuring the spring bar seats completely in the opposing case lugs.

Yes, provided the lug width measures exactly 20mm and the strap is engineered to precise width and thickness specifications. Artisanal, quality straps guarantee total compatibility and superior durability versus industrial production models, with enhanced aesthetic customisation.

With proper maintenance (monthly cleaning, bi-annual conditioning, protection from persistent rain), an alligator or calf leather strap lasts 3–5 years under daily wear. Vegetable-tanned leather develops aesthetic patina over time, increasing the perceived value of the watch.
